Longo | February 17, 1998 |
A high temperature thermal sprayable material, such as a metal or metal oxide, is adhered to the surface of a thermal sprayable plastic particle to form a cladding layer thereon. The high temperature material cladding layer provides a thermal barrier that allows use of the plastic in a high temperature thermal spray process to create a duplex coating containing plastic.
